Pankonin, Chicago, Ill., assignor, by mesne assignments, to Triangle Tool & Mfg. Co., Chicago, III., a corporation of Illinois Original application Aug. 25, 1955, Ser. No. 530,579, now Patent No. 2,832,959, dated May 6, 1958. Divided and this application Oct. 4, 1957, Ser. No. 688,351 6 Claims. (Cl. 254-28) This invention relates to improvements in a stapling device, particularly the hand operated desk type, using preformed staples and usable also as a tacker. This application is a division of the application of William G. Pankonin, Serial No. 530,579, filed August 25, 1955 for stapling Device, now Patent No. 2,832,959, issued May 6, 1958.

This specific invention relates to the provision of separable staple removers Which are normally secured to the stapling device.

When stapling machines are used, and a mistake in stapling is made, it is necessary to remove such staples at once. If a separable remover is used it is sometimes difiicult to find. Also such removers are often lost. Since the removers of this invention are normally attached to the stapling machine these disadvantages are not present.

An object of this invention is to provide such device with a base in which is detachably carried a plier-type remover for clinched staples so as not to interfere with the use of the device for driving and clinching staples and for driving staples as a tacker.

Another object of this invention is to provide such device with a base in which there is detachably carried a staple lifter of the lever type arranged so as not to interfere with the dual use of such device and capable of being carried by such base simultaneously with a staple remover of the plier type.

These objects are obtained by the stapling device hereinafter described and illustrated in the accompanying drawing, in which:

FIG. 1 is a view in side elevation of a stapling device embodying the present invention with a part broken away and shown in section;

FIG. 2 is a view in right-hand end elevation of the stapling device shown in FIG. 1;

FIG. 3 is a sectional view taken on the line 3-3 of FIG. 1;

FIG. 4 is a view in side elevation of a cooperable jaw remover for staples the legs of which are clinched, such remover being removably carried at the right-hand end of the staple carrying device of FIG. 1;

FIG. 5 is a view in side elevation of the staple remover of FIG. 4;

FIG. 6 is a sectional view taken on the longitudinal axis of the base of the stapling device of FIG. 1, illustrating the staple lifter detachably carried in said stapling machine; and

FIG. 7 is a sectional view taken on the line 77 of FIG. 6 with the staple lifter withdrawn to illustrate the holding spring.

The stapling device illustrated in the drawing is similar in general function and usage to that shown and described in Patent No. 2,311,412 issued to William G. Pankonin on February 16, 1943. The stapling device of this invention embodies improvements in its elements and in their cooperation, and, in addition, includes a staple remover and a staple lifter removably carried on the base of the stapling device without interfering with its functioning as clinching device and as a tacking device.

As a foundation for the following detailed description of the base and its adaptability to carry a staple lifter and remover, it is necessary to know that a staple driving handle 79 mounted on pivot 14 forces a staple driving blade 77 downwardly on an ejection chute at the forward end of a staple magazine casing 50 to drive staples and deform their legs on an anvil 34 on the base of the device. The staple magazine is also mounted on pivot 14 and has staple pusher slidable therein with hooks 66 engageable with pivot when the pusher is at the loading end of the magazine.

The base of the stapling device comprises a molded lower member 10 which is secured to a metallic frame having a bottom 11 and sides 12. At the right-hand or loading end of the base the sides 12 have upward extensions 13 perforated to receive a pivot 14 on which the staple driving mechanism is pivoted. The extensions 13 miday of their height are provided with inward depressions 15 forming a bearing surface of substantial length for the magazine casing to guide it separately from the action provided by the upper portions of the extensions 13 for the staple driving arm. The magazine and staple driving mechanism are normally maintained in the material receiving position, shown in FIG. 1, by a riser mechanism including a bridge member 16 secured to the base. Such bridge member supports a riser spring (not shown) above the bottom 11 to provide clearance for the removably carried staple lifter (see FIG. 6). A riser bar 17 has ends slidably guided in slots 18 for limited vertical movement.

From the rear edge of the extensions 13, slots 20 extend forward in said extensions to receive the long wings 23 of a cooperable jaw staple remover 22, shown in FIGS. 4 and 5. This remover functions in general as described in Patent No. 2,033,050 issued to William G. Pankonin on March 3, 1936. It is inserted on its side with its pivoted end forward between the sides 12 from the rear end of the stapling device. The wings 23 project upwardly through the slots 20 outside of the extensions 13 as shown. The short wings 24 loosely fit in grooves 25 formed in the molded member 10. When the remover 22 is in place, seats 26 in the jaws will be resiliently forced over dimples 21 on the sides 12 to hold the remover in such position. To disengage the remover, the wings 23 are grasped and pressed together to move the seats 26 off the dimples 21. The remover can then be withdrawn for separate usage.

A lever-type lifter 27 for staples which have been driven into material with the legs unclinched is also removably carried in the base on the bottom 11. Its handle is inserted under the bridge 16 and its fulcrum seats in aligned holes 32 and 33 in the bottom 11 and molded member 10. The staple lifter 27 is detachably held by a spring 28 seated in the base with two inwardly biased arms with seats 29 engaging opposite sides of such lifter. The spring 28 has knobs 30 fitting in holes 31 in the sides 12 to hold it in position. In FIG. 6 the lifter 27 is shown in place. To remove it the exposed end is simultaneously lifted and drawn outwardly to disengage the lifter from the seats 29 and slide it from under the bridge 16. The fulcrum of the lifter will clear the hole 32 during this action. To insert the lifter, its handle is slid under the bridge 16 and its outer end moved downward and inwardly spreading the arms of the spring 28 until its edges rest in the seats 29.

Both the remover 22 and the lifter 27 are mounted so as not to intefere with each other and with the operation of the device as a staple clincher or a tacker. The end of the staple pusher mechanism will clear the body of the remover 22 as the staple magazine and driver are swung to tacking position.
